I use this workaround to fix tearing on my mediacenter
powered by a intel baytrail hardware.
https://wiki.archlinux.org/title/Firefox/Tweaks#Enable_Legacy_OpenGL_compositor until v88, it was working fine. With v89, the setting layers.acceleration.force-enabled=true has no effect. The "about:support" page reports Compositing: webrender (software) whatever the value true or false. I had to downgrade to v88. |
This task depends upon
EDIT:
I asked to the support :

If it is true, the wiki about the tearing workaround should be updated :
https://wiki.archlinux.org/title/Firefox#Tearing_video_in_fullscreen_mode
gfx.webrender.force-disabled = true
layers.acceleration.force-enabled = true
However, it will not be possible after v92 :
